Benefits of technology
This approach decreases collisions and reduces standby times, preventing performance degradation by allowing legacy and high-throughput terminals to transmit in different intervals, thus enhancing overall network efficiency and power saving efficiency.
Problems solved by technology
Currently, with a rapid increase in the use of the WLAN and the number of wireless terminals, the efficiency of the wireless WLAN has emerged as an issue in a highly dense environment.
However, in the existing frequency band, such as 2.4 GHz or 5 GHz, legacy terminals do not follow a RAW operation and thus, the RAW may be readily introduced.
However, since such beacons are generally used to enhance a network discovery rate and do not have traffic indicator map (TIM) information, it may not be possible to prevent terminals from transmitting PS-polls at a time at a transmission point in time of a beacon.

Embodiment Construction
Object
[0008]Embodiments provide a method that may prevent an occurrence of contention by distributing a transmission interval of terminals so that different device types of terminals may perform transmission in different time intervals even in 2.4 GHz and 5 GHz, and may prevent a degradation in the network performance by a legacy terminal by enabling a terminal, such as 11ac terminal and 11ax terminal, to perform transmission in a time interval different from a time interval of the legacy terminal.
[0009]Embodiments also provide a method of enhancing the transmission efficiency by distributing a transmission interval based on a device type that may prevent a degradation in the overall network efficiency and may also prevent contention from occurring at a specific point in time, when a legacy terminal is mixed.

Provided is a wireless communication method performed at an access point to enhance the transmission efficiency in a wireless local area network (WLAN) system, the method including scheduling a transmission time of an enhanced traffic indicator map (TIM) frame based on a type of a station, and transmitting a second beacon including the enhanced TIM frame to the station at a point in time aside from a transmission point in time of a first beacon.
Description
TECHNICAL FIELD[0001]Embodiments relate to technology for performing wireless communication by distributing a transmission interval based on a type of a terminal in a wireless local area network (WLAN) system.RELATED ART[0002]In general, a local area network (LAN) that is a near field communication network is divided in a wired LAN and a wireless LAN (WLAN). The WLAN employs a method of performing communication on a network using propagation instead of using a cable. The WLAN has been introduced as an alternative for overcoming difficulties found in installation, maintenance and repair, and movement by cabling. According to an increase in mobile users, a need for the WLAN is also increasing.[0003]The WLAN includes an access point and a station (STA) that is a terminal device. The access point refers to equipment that transmits propagation so that WLAN users present within a transmission distance may connect to the Internet and utilize a network. The access point may serve as a base ...
